A Nepalese tourist allegedly plied his friend's flatmate with tequila then repeatedly raped her as she slept before fleeing Australia hours later.

Balram Shiv, 35, now languishes in a Sydney jail cell after being extradited from the U.S., charged with raping and molesting the 21-year-old woman in June 2017.

Early the next morning he caught an Uber to Sydney Airport and flew home to New York where he simply resumed his life as an aviation engineer.

But his self-indulgent social media posts bragging about his decadent lifestyle led to his arrest when the woman identified him to NSW police as her alleged rapist.

The Nepalese citizen, living in the U.S. on a green card, arrived in Australia on June 9, 2017, and stayed with two female friends at an apartment in Carlton.

On the night of June 13 he brought home a bottle of tequila, an affidavit filed to the U.S. District Court for the Eastern District of New York alleged.

Shiv convinced the alleged victim, who had never drunk tequila before, to take four or five shots as they and one of his friends quickly finished the whole bottle.

The victim claimed in the affidavit that she blacked out and later woke up on a mattress on the floor of her room as Shiv was molesting her.

Shiv allegedly pulled her legs apart and performed several sex acts on her despite her telling him not to - and she wasn't strong enough to stop him.

The woman passed out again and allegedly woke up to Shiv raping her as she drifted in and out of consciousness.

'The victim continued to plead with Shiv to stop, but felt very sick and passed out again. When she awoke, she vomited four times on her pillow,' the affidavit read.

'Because of her state of intoxication, the victim was unable to raise her head from the pillow before passing out again.'

The affidavit claims about 9.50pm the other woman heard the allegedly victim yelling 'I don't want, I don't want'.

Another woman later arrived at the flat and when she opened the door, saw Shiv get up from the mattress and heard the alleged victim crying.

She left and returned with her uncle and they asked her what happened.

'I didn't want to do that, he forced me... I know I have a boyfriend. I didn't want to do that. He forced me,' the alleged victim told them, according to the affidavit.

'I cannot fulfill my father and mother's dreams now.'

Shiv made numerous self-indulgent social media posts bragging about his decadent lifestyle, including posing with this flash car

Shiv organised a fundraiser for the National Kidney Foundation for his 35th birthday in November, and later posted photos of him celebrating the milestone with a rich cake, bottle of red wine, and balloons

Among Shiv's numerous travel photos was this one of him lounging in a pool. Each of his photos is accompanied with a pithy, often cringeworthy, line

Shiv's other friend, who also lived at the flat, arrived home about 11pm and asked the alleged victim if Shiv raped her and was told 'yes he did'.

The alleged victim claimed she then fell asleep on her bed before waking up to Shiv molesting her again until someone opened the door.

Shiv ordered an Uber to Sydney Airport about 8.30 the next morning and flew back to New York on a 9.39am flight.
